Ingeneralmygogg le provides a two-part'fraine [0' andZEI an; acontinuous ens plate at; adapted tp beclampe'd tothe twoparts er theframe. The hood or frame IQ comprises a single piece of transparentensue 'inat rial formed to provide "atop "portion 4| ,fU-s'ha'pe'dendlportions I 2 and two "returning lower orhott'om' portions 1 3separated at their ends. The hood may have its entire front edge l4lying in a singleplane, while its rear edge at the top portionis'concaved or recessed as shown at l 5 and the bottom portions likewisecut inner: edges. Thesepinsfcoacti withthe applied border member ashereinafter explained.

'Ifh'e'lens plate at; is'show'n as a single fiat piece of transparentmaterial adapted'to rest against 'thefront' edge of the frameshowninFig. 2. It is provided With a recess}! in its lower portion forthe nose of "the "wearer and has three small notches 32, 33' and 33 toreceive the'three pins l8,i9'andi9. I v l The lens platfe 'ti! ishorifially heid a'gaiiist the frame or hood H] by a retaining or'bordermember '20 Which is a loo'pl-shaped in cross section and thus having afront portion 2| adapted tolie against the face ofthe lens'plate' and arearwardly'projecting skirtpo'rtion 22" to embrace the fr'amelfl. I U Atthe center of the front the bordermerrihe'r is with 'n pfirti'ellybnicai portion '23 adapted to fit overth wearers nose. This." portion23merges at its twolower corners with'the face portion 21 on theoppositesides thereof; and

at the apex of the'nose portion thereflisa head portion 25 continuingupwardly to' the face por tion of the bordermember'at thetop,-thnsbraoing the forwardly bowed'n'o's'e portion. The face portion?!is provided withlrearwardly open recesses the frame; mpAccordinglywhenthe lens plate is against-the 'framefand theretaining memberpositioned over the lenspiate the three parts forma unitary device. e Tohold the retaining member on the frame,

'thus holdingthe 'le'ns' plate in place, I provide a pairofperforatedears 2i at the ends of the retaining member and I mount inthese ears Wire loops lll which are adapted to'coact with the'ears I 7o'n'the frame In to hold the parts together.

In'the construction shownin Figs. 1. to 4, the

wire loop "dllh'as intermediate portion freely occupying the opening inthe ear 2'! and the two arms extending rearwardly and each turhedinwardlyas at 42. The wo inward portions align and when thego ggleisasseinbIed occupy the jperforationin the name; ear I lin alignmentWith'eachbtheras showiiin'Figi. Theloop do is 'aresilient materialandhence'its twearms may be rearwardly spread whenever des ed, and whenspread the inturned ends 42 become free from the ear I! and allowthe'disconnectionof the retaining member "and the removal ofth'e lensplate. Then in reassembling thejp'a'rts the free ends of the two'lo'ops40 are sprung apartby the operators fingers and the free ends"tiinserted in the ears l'IQa fterWhiCh their resilience holds tnemereqtiva n place, thus maimammg the goggle in assmbledcofidition.

Suitable means are provided for holding the face of the U-shaped ends ofthe frame I they extend in use rearwardly in a position suitable forcomfortable wearing by the user. They may also be folded down into thespace Within the frame I for convenient packing or carrying of thegoggle.

The temple is readily pivoted to the frame by having a flattened endmounted between a pair of bosses 54 and 55 (Fig. 6), integral with theend portions I 2, and a suitable pin 56 passing vertically through thebosses. This pin has its lower end exposed in an external recess 57 inthe U-shaped end of the frame. The pin does not extend beyond the outerperiphery of the U- shaped portion but the end of the pin is accessiblein the recess so that it may be readily withdrawn by a pair of pliers,thus the temples may be readily attached or removed if desired.

In place of the temples shown in the drawing, one may, if desired, use astrap adapted to pass around the Wearers head, the ends of the strapbeing secured to the ears H. is illustrated in Fig. 8, where 60indicates the strap and 6! a wire loop attached to the strap and havinga free end portion passing through the opening in the ear [1. In thiscase the wire fastening loop 62 (similar to the loop 40 but slightlylonger) has its inturned free ends 63 occupying the ear 2'! and itsintermediate portion 64 looped around the ear I 7 and retained by theoverlying fastening 62.

It will be seen therefore that the change from temples to strap as theholding means may be ver readily effected. It is simply necessary towithdraw the two pivot pins 50, to substitute the loops 62 for the loops40 and to pass the fasteners 6| through the ears of the hood ends.

It will be seen that my goggle, which may be readily made of transparentplastic material,

is very light and is comfortably worn and may be. readily separated tofree the parts so that the lens plate and the frame members may beeasily cleaned. The separable provision also allows for changing thelens plate; substituting a colored plate, for instance, if desired, forthe work in hand. The parts while very light are comparatively strong.The front retaining member is well braced by the bead extending from thenose piece to the upper portion thereof without interfering with thevision. The border member forms a front projection to the lens plate andallows the device to stand lens down on a bench,

for instance, without danger of the lenses becoming soiled.

I claim:

1. In a goggle, the combination of a frame having a top portion, endportions and a pair of separated bottom portions, the rear edge of theframe being formed to fit approximately against the face of the wearer,a movable lens plate adapted to bear against the frame at the front,

of the frame, and having a rearward flange adapted to embrace the frame,said retaining member being movable from the frame to allow the readyinsertion and removal of the lens plate between them, the retainingmember being provided with cars at its ends and loop portions adapted toconnect said ears removable to the end portions of the frame.

2.-In a'goggle, the combination of a frame having a top portion, endportions and a pair of separated bottom portions, the rear edge of theframe being formed to fit approximately against the face of the wearerand the front edge lying Such construction I p an open retaining memberhaving a contour approximately corresponding to that of the frontsubstantially in a single plane, a flat lens plate adapted to lieagainst the front edge of the frame and having a notch on its lowerportion for the "wearers nose, a retaining member in the form of acontinuous open loop and for the most part having a contourcorresponding to the front of the frame, and having a flange to embracethe frame, the retaining member being connected to the frame adjacentthe free ends of the separated bottom portions of the frame and havingan outwardly bowed portion registering with the notch in the lens plate,and readily releasable means normally connecting opposite ends of theretaining member with the ends ofthe frame whereby the retaining membermay be readily spaced from the frame to allow the insertion and removalof the lens plate. a

3. In a goggle, the combination of a frame having a top portion, endportions and a pair of separated bottom portions, the rear edge of theframe being formed to fit approximately against the face of the wearerand the front elge lying substantially in a single plane, a flat lensplate adapted to lie against the front edge of the frame and having anotch on its lower portion for the wearers nose, a retaining member inthe form of a continuous open loop and for the most part having acontour corresponding to the front of "the frame and having a flange toembrace the exterior of the frame, said retaining member continuingacross the open notch in the lens plate in the form of an outwardlybowed portion registering with said notch, the flange of the body memberat opposite ends being provided with perforated ears, and a pair of loopfasteners occupying the perforations and normally extending along theouter side of the end portions of the frame and coacting with outwardlyextending ears on such end portions to hold the retaining member inposition against the frame with the lens plate clamped between theretaining member and frame, said fasteners being separable from theframe ears whereby the retaining member ma be readily spaced from theframe to allow the insertion and removal of the lens plate.
